Hi Gaoyang,
Before attempting to start your development effort, I definitely recommend
using an HL7 test client, just to verify that MLLP communication is possible
with the server. A free test client called "Interface Explorer for HL7" is
available for download here: http://www.laconic-designs.com/index.html
Because this test client is configurable, it will allow you to easily send test
messages via MLLP to any IP address and port without any Java development. Once
you verify that communication is possible with this test client, you should
gain the confidence you need to continue with your work.

Hi Erik,
Thanks for your reply.I have another question.
Our company's VPN IP is 122.195.58.53 .
Our company'name is A, the another is B. The B company connect to our's
VPN using their PC which IP is 192.168.10.32.
The PC with 192.168.10.11 in our company is the client which
sending HL7 message , and the PC with 192.168.10.32 in B company is the server
which receiving the hl7 message. And the server's port is 6660. And B company
tell me that the 6660 port is open.
Now I try to telnet 192.168.10.32 6660,but I fail.Then I ask them why I
can not telnet 6660.They tell me that 'the Port 6660 is only available for MLLP
calls, and it cannot be accessed by telnet. ' So I do not know how I can
connect to 6660. Using the ' Socket s = new Socket(192.168.10.32, 6660)' to
connect to 6660?
'
And the B company tell me that they can use two servers to test that
work using our VPN. So I think our Firewall have no problem.

Hi Gaoyang,
There may be several reasons why you cannot telnet to a specific port. By
default, telnet servers listen at port 23. In order to telnet to port 6660, the
telnet server at that IP address needs to be set up to listen at that port. In
addition, that port would need to be open (not obstructed by a firewall etc).
While port 6660 may be set up on that server to be dedicated for MLLP
communication, make sure there are no obstructions that prevent the server from
actually receiving messages at that port.

Subject: [HAPI-devel] sending Hl7 message via MLLP
Dear friends,
I have a question. I am doing a test about sending HL7 message via
MLLP.We have two servers in our company that works using VPN. The PC with
192.168.10.11 is the client with sending HL7 message , and the PC with
192.168.10.32 is the server with receiving the hl7 message. And the server's
port is 6660.
Now,I can ping 192.168.10.32,but can not telnet
192.168.10.32 6660. Someone tells me that 'Port 6660 is only available for
MLLP calls, and it cannot be accessed by telnet. ' Is it right? In my code,I
get the connection to the server of 192.168.10.32 like this :the flowing codes:
connectionHub = ConnectionHub.getInstance();
// A connection object represents a socket attached to an HL7 server
connection = connectionHub.attach(“192.168.10.32”, 6660, new PipeParser(),
MinLowerLayerProtocol.class);
public Connection attach(String host, int port, Parser parser, Class llpClass)
throws HL7Exception {
Connection conn = getExisting(host, port, parser.getClass(), llpClass);
if (conn == null) {
try {
//Parser p = (Parser) parserClass.newInstance();
LowerLayerProtocol llp = (LowerLayerProtocol)
llpClass.newInstance();
conn = connect(host, port, parser, llp);
} catch (ClassCastException e) {
//Log.tryToLog(cce, "Problem opening new connection to " + host
+ " port " + port);
throw new HL7Exception( "ClassCastException - need a
LowerLayerProtocol class to get an Inititator",
HL7Exception.APPLICATION_INTERNAL_ERROR,
e);
} catch (Exception e) {
//Log.tryToLog(e, "Problem opening new connection to " + host +
" port " + port);
throw new HL7Exception( "Can't connect to " + host + " port " +
port + ": " + e.getClass().getName() + ": " + e.getMessage(),
HL7Exception.APPLICATION_INTERNAL_ERROR,
e);
}
}
incrementRefs(conn);
return conn;
}
private Connection connect(String host, int port, Parser parser,
LowerLayerProtocol llp) throws UnknownHostException, IOException, LLPException {
Socket s = new Socket(host, port);
Connection i = new Connection(parser, llp, s);
connections.put(makeHashKey(host, port, parser.getClass(),
llp.getClass()), i);
sockets.put(makeHashKey(host, port, parser.getClass(), llp.getClass()),
s);
return i;
}
but when I try to connect to the 192.168.10.32 on port 6660: I get the
failure:
ca.uhn.hl7v2.HL7Exception: Can't connect to 192.168.10.32 port 6660:

I do not find the reason why I can not connect to the 192.168.10.32 on port
6660.
Then someone tells me The SNMP service should be open in the firewall,is it
nessary? I hope to hear your opion.Thanks verry much.
Thanks,
gaoyang
